Uncle Jaque's info (1860) seems to place it a whole lot older than 1926, which I figured was not the beginning point anyway. Note the spelling of Haskell/Hascall, obviously the same person intended. Since writing my earlier posts, I have found several instances of the Hascall/Bradbury authorship. I was in hopes of finding it at Cyber Hymnal under the Land of Beulah title, but no luck there, or anywhere else for that matter.
Here is the listing of recordings given by The Folk Music Index, I am sure that at least some of them are available on CD, though not listed as such. And there are other recording not listed, notably the Stanley Brothers.
